Abstract: A corrosion-resistant fiberglass spinner is prepared by applying consecutive, alternating layers of chromium and nickel to the bores of the spinner, and thereafter thermally interdiffusing the chromium and nickel to form a corrosion-resistant coating.

Abstract: A durable, corrosion-resistant fiberglass spinner is prepared by applying a uniform layer of titanium nitride to the bores of the spinner by chemical vapor deposition, and applying over the layer of titanium nitride a layer of platinum by transient liquid phase deposition.

Abstract: An alloy suitable for use as a spinner in forming glass fibers, the alloy being cobalt-based and including higher amounts of nickel and lower amounts of cobalt than used in typical cobalt-based superalloys.

Abstract: Cobalt based alloys which include chromium, nickel, tungsten, tantalum, zirconium, carbon and boron are provided which are suitable for forming spinners to be used in forming glass fibers. The alloys contain critically important amounts of carbon which maximizes the stress rupture life of the spinner alloy and minimizes the creep rate thereby making the alloy outstandingly adapted for glass manufacture.

Abstract: An alloy suitable for use as a spinner in forming glass fibers is provided. The alloy has outstanding stress rupture-life and is highly resistant to the erosion and corrosion of molten glass. The alloy is a cobalt-based alloy and further includes the following in approximate percent by weight, Carbon 0.5 to 1.0; Silicon 0.01 to 0.15; Chromium 30 to 40; Nickel 5 to 15; Tungsten (Wolfram) 4 to 7; Yttrium 0.5 to 1.5; Tantalum 2 to 5; Boron 0.005 to 0.04; Zirconium 0.1 to 0.4. The alloy typically will include the following as impurities, the amounts indicated being in percent by weight unless otherwise set forth: Aluminum 0 to 0.2%; Titanium 0 to 0.2%; Manganese 0 to 0.01%; Iron 0 to 1%; Phosphorous 0 to 0.005%; Molybdenum 0 to 0.10%; Sulfur 0 to 0.005%; Bismuth 0 to 0.5 ppm; Lead 0 to 5.0 ppm; Selenium 0 to 5.0 ppm; Silver 0 to 50 ppm; Nitrogen (N.sub.2) 0 to 150 ppm; Oxygen (O.sub.2) 0 to 50 ppm.

Abstract: A process for producing atomized, powdered metal or alloy is disclosed. Streams of molten metal or alloy are forced through orifices whose openings are so small that the surface tension of the molten metal or alloy would otherwise prevent the flow of molten metal or alloy through the orifice.

Abstract: An increase in fine particle metal production is realized when the descending molten metal stream is caused to impinge upon one of two descending fluid streams at a locus offset from the locus of intersection of the two descending fluid streams.

Abstract: An improvement in the manufacture of fibrous glass products is provided by employing a bushing in which the bottom wall, or tip plate, is fabricated of a properly aligned dispersion strengthened precious metal, or alloy thereof.
